b all whom it may concern Be it known that I, .lilnnxnlvnna VVINTON, citizen of the United States, residing at Lakewood, in the county of Cuyahoga and State of Ohio, have invented certain new and use ful Improvements in Air-Supplies for In and communicating by means of separate passages with the several cylinders, the

particular object of this construction being to enable the air supply to be obtamed trom a pipe leading to the outside of the building; to muiilc thev noise, arranged so that the air is thoroughly heated in passing to the cylinder. I

The invention may be further briefly summarized as consisting in the construction and combination of parts hereinafter set forth in the following description, drawing and claim Referring to the drawings Figure 1 is an elevation of the exhaust side of the engine showing; the parts broken away; Fig. 2 is an end elevation of the first cylinder and is a view taken behind the governor with E-ZtTLtS broken away and in section; Fig. 3 is a plan view of a unit of two cylinders with the head of one removed and with the head of the other broken. away, other parts being shown in plan and section; and F 1g. at is a view of the upper portion of the same unit with parts broken away and in section.

The crank case may be of any desired construction, and its details together with the crank shaft and its bearings are not shown, for the reason that they form no part of the invention, and may be of any preferred arrangement.

The crank case comprises a base 1 mounted upon a suitable support 2 and carrying the upper crank case member 3. These parts inclosee. suitable crank shaft up on which is mounted the balance wheel 4. The forward portion oi the crank case is adapted to receive suitable gearingand another 'rnecbanisin for operating an air'pump 5,

which is provided with to furnish air under pressure for the fuel mixture supplied to the engine. The crank shaft also operates a governor 6, whose internal construction is unimportant, but the usual grooved member 7 for controlling the fuel supply as will later appear.

The upper half 3 of the crank case is provided on. the exhaust side of the engine in the upper corner with a longitudinally disposed channel or passage 8 communicating with a suitable pipe 9 preferably leading to a point outside of the building so as to muille the noise of the air intakes which are connected to this channel. At each of the cylinders channel 8 has a side port 10 for a purpose to be described.

Six cylinders are preferably employed, each comprising a main cylinder body 11 provided with a suitable water jacket 12 and a lower supporting flange 13 adapted to be secured to the upper member 3 of the crank case. Each cylinder, at, its upper end,.is faced off to receive the cylinder head structure to be described. At the upper end of the cylinder the face is cut away at l t exhaust side and preferably toward. one sidewith a cast metal air inlet member 21 having a passage 22 therein communicating with one of the air supply ports 10, and wl'lose/upper end is. finished with the top of the cylinder. Diametrically opposed to this air inlet member is a pet-cock or relief valve 23 of any desired structure, in communication with the interior structure through a suitable passage 24:, shown in dotted lines in Fig. 3. This pet-cock and relief valve may be utilized for any of the purposes to which such devices'are applicable.

Each cylinder is provided with a head which is hollow to form a water space. Integral with the wall of the head are suit- At a lower point on the These valves may be 'air intake valves.

able vertically disposed ribs 26 provided Wit-h openings for receiving suitable bolts or studs 27, for The head is provided upon its bottom with an exhaust valve opening 28 having a seat 29 and with an air inlet opening 30 provided with a seat 31. A suitable exhaust housing 32 extends into the hollow head and establishes communication between the opening 29 and an opening 33 in the exhaust elbow 34, extending out beyond the side of the cylinder. This elbow and housing are formed integral with the head and with a water jacket elbow portion 35, these parts terminating in a horizontally disposed flange 36 beyond the side of the cylinder.-

Opening 30 communicates with an air inlet housing 37 formed integral with the head and extending out and in communication with an air inlet elbow 38, the lower edge of said elbow being finished and being tlush with the lower edge of the head and ar- 'angcd in position to communicate with the channel 22, in the air inlet member 21. The. water jacket portion of the exhaust elbow structure is provided with suitable ports, 39, preferably three in number, extending through the flange 36. as shown in Figs. 2- and L. Each head 25 is also provided with a water outlet connection 1-0 terminating in a horizontallydisposed lia'ngc +1, asshown in Fig. 2. v

Each cylinder is provided with a main air intake valve 42, controlling the passage of: air from the air intake housing to the cylinder, and valve 43 controlling the exhaust. operated by suitable rockers M loosely mounted upon a shaft 45 supported in brackets E6 secured to the cylinder head. Each of these rockers is provided with a friction roller 47 engaging a suitable cam 48 mounted upon a cam shatt 49 actuated in any suitable manner from the crank shaft.

In the engine described, the main volume of air supply to the several cylinders comes in through a common passage or channel opening at the outside of the building and therefore mutlling the sound or noise of the Said passage is in the crank case where it is out of the way and communicates with the several air passages, one leading up :uljacent to and supplying each cylinder. This arrangement thoroughly heats the air by otherwise waste heat from the engine and therefore increases etliciency. -'1he air in et and exhaust elbows also terminate in finished lower ends in substantially the same plane with the cylinder holding the head in place. 7

' channel, and means for qng in conpinction with said head and having a channel leading to the inlet valve mechanism, an air inlet member carried by the cylinder and supplying air to said air inlet member.

2. In an explosive engine, a plurality of cylinders, a cylinder head for each cylinder having an air inlet and exhaust, an air inlet housing connected to said head and leading in communication with said to the air inlet valve mechanism, a series of communicating air inlet members carried by said cylinders and in communication with ti 5 air inlet housing, and a single conduit for supplying air to said air. inlet members.

3. In an explosive engine, a crank case having an air supply channel therein, a

cylinder mountedupon said crank case and having an air inlet channel leading from the channel in the crank case to the main air inlet, and an air inlet valve for controlling the admission of air to the cylinder.

t. In an explosive engine, a crank case having an air supply channel therein, a cylinder mounted upon said crank case, an air inlet member carried by said cylinder and in connnunieation with said air supply channel in the crank case, a head for said cylinder having an exhaust opening and an air inlet opening, an air inlet housing communicating with the air inlet opening and in communication with the air inlet member, and means for supplying air to the air'supply channel in the crank case.

5. in an explosive engine, a crank case, a cylinder mounted thereon and having an air inlet member rigidly secured to the side thereof co-extensive therewith and having an open upper end substantially in horizontal plane with respect to the top of the cylinder. a cylinder head secured to said cylind and having an exhaust opening and an inlet opening, and an air inlet housing extending from the air inlet opening and terminating in an elbow communicating with the air inlet member secured to the side of the cylinder.

Tn testimony whereof I ailix my signature.

ALEXANDER WINTON.
